Some tips on 42923-77-3

42923-77-3 6-Methoxy-1,2,3,4-tetrahydroisoquinoline 39356, atetrahydroisoquinoline compound, is more and more widely used in various.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.42923-77-3,6-Methoxy-1,2,3,4-tetrahydroisoquinoline,as a common compound, the synthetic route is as follows.

A mixture of 6-methoxy- 1,2,3,4-tetrahydroisoquinoline (1.0 g, 6.13 mmol), ethyl 3-iodobenzoate (2.03 g, 7.35 mmol), Pd(dba)2(352 mg, 0.61 mmol), Cs2C03(7.98 g, 24.5 mmol) and X-phos (584 mg, 1.23 mmol) in DMF (15 mL) was degassed and purged with nitrogen for three times. The resulting mixture was stirred at 100C for 2 hours under nitrogen. The reaction mixture was cooled to room temperature and diluted with H20 (30 mL), and extracted with EA (20 mL X 2). The combined organic layers were dried over anhydrous Na2S04, filtered and concentrated to dryness. The residue was purified by chromatography on silica gel using 5-10% EA in PE as eluent to give the title compound (1.12 g, 58.7%) as a yellow liquid. +ESI-MS: m/z 311.7 [M +H]+.
